Western Mediterranean shelf-incised submarine canyons: multi-proxy evidence of ...
López-Quirós, Adrián; Puga-Bernabéu, Ángel; José Lobo, Francisco; Ruíz-Caballero, Elvira; Cerrillo-Escoriza, Javier; Pérez-Asensio, José N.Submarine canyons play a critical role in continental margin sediment transport, functioning both as sediment traps and conduits. This study examines the depositional dynamics of the Motril, Carchuna, and Calahonda canyons in the northern Alboran Sea (western Mediterranean) to assess their role in Holocene sediment storage and transfer. Comprehensive sedimentological and elemental geochemical analyses reveal di...
Incised valleys on the Algarve inner shelf, northern Gulf of Cadiz margin: stra...
Carrión-Torrente, Álvaro; Lobo, Francisco José; Puga-Bernabéu, Ángel; Luján, María; Mendes, Isabel; Hanebuth, Till J. J.; Lebreiro, SusanaA network of cross-shelf paleovalleys has been recognized over the paleo-inner shelf off the Gila & SIM;o-Almargem Estuary, a small fluvial drainage system that presently receives minor sediment supply in the eastern Algarve shelf, northern margin of the Gulf of Cadiz (SW Iberian Peninsula). This study is aimed at determining the driving controls that triggered substantially different paleohydrological conditio...
Origin and driving mechanisms of marine litter in the shelf-incised Motril, Car...
Cerrillo-Escoriza, Javier; Lobo, Francisco José; Puga-Bernabéu, Ángel; Rueda, José Luis; Bárcenas, Patricia; Sánchez-Guillamón, OlgaIntroduction and methodsMarine litter density, distribution and potential sources, and the impact on canyon seafloor habitats were investigated in the Motril, Carchuna and Calahonda canyons, located along the northern margin of the Alboran Sea. During the ALSSOMAR-S2S oceanographic survey carried out in 2019, canyon floor imagery was collected by a Remotely Operated Vehicle along 5 km in the Motril Canyon, 10 k...
An enigmatic kilometer-scale concentration of small mytilids (Late Miocene, Gua...
Aguirre, Julio; Braga, Juan C.; Martín, José M.; Puga-Bernabéu, Ángel; Pérez-Asensio, José N.; Sánchez-Almazo, Isabel M.; Génio, LucianaUpperMiocene heterozoan carbonates crop out extensively in a NE–SW-trending belt (42 km long and 1.5–8 km wide) along the so-called El Alcor topographic high, fromCarmona to Dos Hermanas (Seville, S Spain). These carbonates formed at the southern active margin of the Guadalquivir Basin, the foreland basin of the Betic Cordillera. They change to marls basinward (NE) and to sands landward (SE and SW). Therefore, ...
